The savanna tetra, Hyphessobrycon stegemanni, is a characid from the middle rio Tocantins and rio Araguaia basins in central Brazil. In the hobby its name has often been misapplied to Hemigrammus ataktos, since both occur in the Tocantins and have a dark lateral stripe. Its range lies almost entirely in the cerrado, the tropical wooded grassland of central Brazil.

The Pantanal eartheater, Satanoperca pappaterra, is a cichlid from the rio Guaporé and upper rio Paraguai basins in Brazil, Bolivia and Paraguay. Relatively rare in the ornamental trade and much sought after, it is easily told from all known congeners by a series of prominent black blotches beneath the dorsal-fin and a well-defined dark band along the side of the body. It has been introduced to the upper rio Paraná in southeastern Brazil.
